WHEEL. 7

To all whom it mag concern." a

Be itknown that I, MORRIS "P. HOLMES, a citizen of the United States,residing at Claremont, in the countyfof Sullivan and State ofNewHampshire, have inventedcertain 'new' and useful Improvements inWheels, of which the following is a full, clear, and exactspecification. p i My invention relatesto wheels. if

It has for its object to provide an improved wheel, and more especiallyan improved truck wheel, which is of a simple and rugged constructionadapted to be cheaply manufac tured and to withstand rough usagein-service. A more specific object of my invention is to provideimproved, simplified and rugged means for attaching a wheel to its axleand removably securing the wheel bearings,

whereby the wear is placed upon wear ab sorbing members adapted to bereadily substituted when desired, and whereby the wholemechanism is madereadily accessible.

, These and other advantages of my improved a truck wheel.

construction will, however, hereinafter more fully appear. I r

n the accompanying drawings I have shown, for purposes of illustration,one embodiment which my invention may assume in practice,-illustratingthe sameas applied to In these drawings,

" Figure 1 is a vertical sectional view of of my lnvention 1n posltionon a i Fig. 2 aside elevation of the wheel.

In this illustrative construction, I it will. be

obse v d that the wheell is, carr 1 1 e oute'r"end of'a suitable axle 2,herein a removable stub 3 having body rec- Qtarigular 'crosssectionrigidly connected as by a set screw 3 with the body 4; of the'truck,frame 5, the wheel being operatively con- IlGCtCl to and mounted uponthe axle 2 injan improved-manner and through means hereinafterdescribed. I

The wheel 1 maybe of any suitable" or standard construction and isprovided with "a suitable axially disposed bore or chamber 6 of greaterdiameterthanithe diameter of the shaft '2. In this chamberand' disposed.between the shaft 2 and abearing sleeve 7 fitting the inner wall of thechamber, are suitable frictionjbearings, herein inthe form fof rollerbearingsig; As shown, the inner Lends of these hearings are suitablyspaced as for interlocking these elements, retaining the preferablysimilarly I locatedat their outer V Specification of Letters r'a tentfPatented Aug. 9,1921". Application; filed December 15, 1919. Serial No.344 943, I I I ends,'the construction preferably being such that thebearings andthe washers at their I opposite ends are all disposed-;with.in the ends of the sleeve7. 5 V 'Q Operatively connected to thewheel 1 and, the axle2 is improved means for c'oi'mect ing bearings 8 inposition, andtakingthe wear during service. These means preterahlyinclude, as shown, a plurality of members 11 of semi-disk; form havingsemi-circular cut-- away portions 12 in their adjacent surfaces, adaptedto be receivedin a suitably. formed reduced portion, herein, forexample, an-an} nular groove 13, formed on the outer endwof the shaft2.- As shown, these members 11 unite to form a disk receivable inthegroove 13 when the wheel 1 is pushed inward against the frame andadapted to be received in the outer end of the bore or chamber 6'whenthe wheel is again pulled-outward; Cooperating with these members11' and acting to'hold the same in position, i's also a suitable member,herein a cap 14,-adapted to 'be'attached tothe wheel and'preferablyhaving annular flange 15 tl1ereon adapted to abut.

against the members 11 adjacent theirtpe- 'ripheries and likewise tofibereceived within the outer end of the bore or chamber .6 in

such a manner "as definitely to"p ositi'onf the. 'members 111 andbearings. As shown, this cap '14 is also provided with joppositely'extending hooks 16 on its opposite sides, which,

as shown,are preferably jarcuately slotted 'as at 17in such a manner astofen'able said hooks, when the member 14 is turned in the bore 6, toengage horizontally disposed studs '18 which are carried on the wheel 1on opposite sides of the bore orjchamber '6, and them selves carry nuts19 and suitable lock washers engaged position, to clamp the'partssecurely the fact that thecap 4 is so shaped as to form an 011 11 amber"21 communicating with the bearings "through. the flange 15 ,and thatthe cap is also providedwith an oil inlet plug 22 "Inthe use ofmyimprojvied construction,

'20 adapted, whenthehooks 16 are in this 1 00, together. Here attentionis also directed to sothat this chamber may be conveniently when it isdesired to remove the members '11 or thebearings for any reason, it isonly sembling the parts'when in this position, it

is obviously only necessary to replace the members 11, pull out thewheel, insert and turn the cap, and then tighten the nuts 19, whereuponthe parts are securelyheld in their desired assembled relation.Obviously, the parts may also be lubricated-whenever desired by fillingthe chamber 21 through the inlet 22, the construction being such thatthe' lubricant in the chamber 7 maynave free access to all the workingparts. f

As a result of my improved construction, it will be noted thatpractically all of t'he wear is taken upon the members 11 and that thesemembers are readily removable when desired, the construction being suchthat new members may be'substituted with great facility and withoutnecessarily disassembling the entire mechanism, it only being necessaryto loosen the screws, remove the cap by a simple operation, and push inthe wheel, a process capable of beingper formed in a few moments.Attention is also directed to" the fact that through m improvedconstruction, it is possible to produce 'a wheel of a rugged and readilyaccessible type at relatively small expense, the'fconstruction beingsimple and of 'a type which may be manufactured with a minimum ofmachinin for specialp'arts.

VVhilehave in this application specifically described one form which myinvention may assume in practice,.it will be understood that this formof the same is shown forpurposes of illustration and that thein-,ventio'n' may be modified and embodied in other forms without departingfrom its spirit or the scope of the appended claims.
